This isn't the first time that the Views Module has spit out invalid code. It's not a huge issue, but I've seen Views spit out div blocks without a close tag, just causing me all kinds of headaches in IE.
The block data are clearly saved in the blocks table in the database. But the info field isn't. To get this, one needs to go in two different directions.
So I'm considering an Alfresco installation for a client to be hosted on an XServe Mac OS X Server. Alfresco seems like a viable open source replacement for Sharepoint. And I'd like to believe that, but I'm currently having troubles with the install on my local machine. So I'm going to log my attempt at solving this problem for future posterity.
